The xml.dom contains the following functions:
registerDOMImplementation( |
name, factory) |
-
Register the factory function with the name name. The
factory function should return an object which implements the
DOMImplementation interface. The factory function can return
the same object every time, or a new one for each call, as appropriate
for the specific implementation (e.g. if that implementation supports
some customization).
getDOMImplementation( |
[name[, features]]) |
-
Return a suitable DOM implementation. The name is either
well-known, the module name of a DOM implementation, or
None . If it is not None , imports the corresponding
module and returns a DOMImplementation object if the import
succeeds. If no name is given, and if the environment variable
PYTHON_DOM is set, this variable is used to find the
implementation.
If name is not given, this examines the available implementations to
find one with the required feature set. If no implementation can be
found, raise an ImportError. The features list must be a
sequence of (feature, version) pairs which are
passed to the hasFeature() method on available
DOMImplementation objects.
Some convenience constants are also provided:
- EMPTY_NAMESPACE
-
The value used to indicate that no namespace is associated with a
node in the DOM. This is typically found as the
namespaceURI of a node, or used as the namespaceURI
parameter to a namespaces-specific method.
New in version 2.2.
- XML_NAMESPACE
-
The namespace URI associated with the reserved prefix
xml , as
defined by
Namespaces in XML
(section 4).
New in version 2.2.
- XMLNS_NAMESPACE
-
The namespace URI for namespace declarations, as defined by
Document
Object Model (DOM) Level 2 Core Specification (section 1.1.8).
New in version 2.2.
- XHTML_NAMESPACE
-
The URI of the XHTML namespace as defined by
XHTML 1.0: The Extensible
HyperText Markup Language (section 3.1.1).
New in version 2.2.
In addition, xml.dom contains a base Node class and
the DOM exception classes. The Node class provided by this
module does not implement any of the methods or attributes defined by
the DOM specification; concrete DOM implementations must provide
those. The Node class provided as part of this module does
provide the constants used for the nodeType attribute on
concrete Node objects; they are located within the class
rather than at the module level to conform with the DOM
specifications.
Release 2.5.2, documentation updated on 21st February, 2008.
